env->ExceptionClear();
}
return(getOrientation());
}
QString QmlAndroidOrientation::setOrientationLandscape()

activity.callMethod<void>("setRequestedOrientation", "(I)V", 0);
if(env->ExceptionCheck())
{
qDebug() << "exception occured";
env->ExceptionClear();
}
return(getOrientation());

QString QmlAndroidOrientation::getOrientation()
{
jint orient = activity.callMethod<jint>("getRequestedOrientation");
if(env->ExceptionCheck())
